4Th Ventricle

Abstract A case of hemangioma calcificans in the 4th ventricle is reported. Skull x-ray films demonstrated a dense calcification in the posterior fossa. Computed tomography disclosed a hyperdense mass in the 4th ventricle. The clinical picture was of increased intracranial pressure due to obstructive hydrocephalus. An hemangioma calcificans in the 4th ventricle was removed successfully.

Venous Varix

Abstract Enlarged veins in two vascular malformations blocked the cerebrospinal fluid outflow pathways, causing hydrocephalus. Both patients presented not with the usual clinical picture (hemorrhage, seizure, etc.), but with signs of increased intracranial pressure. Computed tomography and angiography were necessary to understand the pathophysiology. An arteriovenous malformation was responsible for the first patient's headache, and a venous varix was the causative lesion in the second patient. Hydrocephalus caused by a venous varix has not been reported before.

Cerebellar Medulloblastoma

Medulloblastoma is a malignant brain tumor that is typically seen in children. It is classified as an embryonal tumor, classically located within the posterior fossa. When it involves the fourth ventricle, the patient commonly presents with signs and symptoms of raised intracranial pressure secondary to obstructive hydrocephalus. It is exceedingly rare for Medulloblastoma to occur in middle and late adulthood. In this paper, we present a case of a 51-year-old man who presented with a posterior fossa mass that was diagnosed later as Medulloblastoma.

✓ The authors describe a 37-year-old man with the classic clinical features of Hand-Schüller-Christian disease. He presented with symptoms of increased intracranial pressure due to obstructive hydrocephalus secondary to a huge xanthogranuloma involving falx cerebri and tentorium cerebelli. Immunohistochemical and ultrastructural studies failed to demonstrate Langerhans histiocytes, however. The implication of this finding is discussed in light of the recent relevant literature.

Reversible Encephalopathy

In this report, the authors describe the case of a teenage boy who presented with hypertensive emergency, posterior reversible encephalopathy syndrome, and hydrocephalus due to fourth ventricle outlet obstruction. Posterior reversible encephalopathy syndrome is a well-characterized but uncommon syndrome in children that is generally triggered by severe hypertension. The unusual clinical picture of this patient, who had isolated cerebellar edema leading to obstructive hydrocephalus, has been rarely described in children.

Uncommon Location

We report two patients with central neurocytomas at an uncommon location in the brain. The first, a 58-year-old man presenting with signs and symptoms of increased intracranial pressure, had a tumor located at the pineal region. The second, a 21-year-old woman with tumor in the aqueductal region had worsening migraine-like headaches and diplopia. Both patients had obstructive hydrocephalus treated by neuroendoscopic third ventriculostomy and biopsy of the tumors. No additional treatment was done. We conclude that neurocytomas should be considered in the differential diagnosis of tumors located in the pineal and aqueductal regions.

Primary central nervous lymphoma (PCNSL) is a rare variant of extranodal non-Hodgkin's lymphoma with a especially poor prognosis. The diagnosis is usually encountered in immunodeficient patients but is also encountered, albeit uncommonly, in the immunocompetent. We present a 50-year-old male who developed signs and symptoms of increased intracranial pressure. Imaging revealed the presence of a fourth ventricle mass with obstructive hydrocephalus. First, the patient underwent emergency endoscopic third ventriculostomy followed, few days later, by complete tumor resection via a posterior fossa craniotomy. Postoperative histopathology revealed the lesion to be a PCNSL. He received adjuvant chemotherapy and radiation and remained with no recurrence on regular imaging studies for 18-month followup. We report herein the fourth case of isolated PCNSL lesion to the fourth ventricle in the literature and provide the rationale for our belief that craniotomy and tumor resection, if feasible, should be the initial line of management in similar cases to relieve hydrocephalus and achieve the diagnosis.

Pediatric posterior fossa ependymomas are typically well-delineated masses with heterogenous enhancement arising from the floor, lateral aspect, or roof of the fourth ventricle. Growth of tumor into the posterior fossa subarachnoid spaces, particularly into the foramen of Magendie and the cerebellopontine angles via the foramen of Luschka, is a radiological hallmark of this tumor. Clinical findings of elevated intracranial pressure and obstructive hydrocephalus are common at presentation. The current standard of care for children with ependymoma consists of gross total resection with subsequent focal radiotherapy. The extent of resection is the single most important determinant of outcome. Hydrocephalus typically resolves after resection, and it is uncommon to require cerebrospinal shunt placement after tumor removal.

Persisting Intraventricular Fat-Fluid Levels following Surgery on a Ruptured Dermoid Cyst of the Posterior Fossa

Fluid Levels

Intracranial dermoid cysts occasionally rupture spontaneously into the ventricles or into the subarachnoid space. In such cases, intraventricular fat-fluid levels are invariably evident at computed tomography and may even be visible on a conventional radiograph of the skull. A case is described in which fat was observed to remain in the ventricles long after surgical removal of a dermoid cyst. We think that this fat, by causing obstruction of the cerebrospinal fluid pathways, should be regarded as a potential cause of intermittent elevation of intracranial pressure.
